The following schematic presents the basics of the Petfood manufacturing process.
Careful consideration of intake, cleaning and storage of both dry and wet raw ingredients. Dust control, odour control and potential cross-contamination enjoys special attention during design.
The nature and type of wet ingredients to be used in formulations determines the processing technology we apply and the subsequent infrastructure required. Introduction of wet ingredient is introduced into the process at a point where the risk of cross-contamination is minimised.
State-of-the-art batching technology and equipment is used to very accurately batch both dry and wet ingredients. Ottevanger also manufactures and supplies the latest technology in handling and batching of macro and micro ingredients such as vitamins and minerals. Cross contamination between batches is minimised through proper process design.
Efﬁciency of thermal processing and appearance of ﬁnal product relies to a large extend on proper size reduction of raw ingredients. Ottevanger Hammermills are designed to deliver accurate particle size distribution curves and equiped with automatic screen change solutions make operational management a breeze. Course and ﬁne grinding solutions are tailored to retain ingredient quality while meeting size reduction requirements.
The choice of extrusion technology is determined by raw ingredient, formulation and ﬁnal product requirements. Semi moist petfoods and treats require a completely different approach in terms of introduction of fresh meat or ﬁsh into the process as well as conveying to the down-stream process steps. Online process control of operating conditions ensures optimum ﬁnal product quality. Odour control becomes vital from this point down stream the process.
Different approaches are followed for drying and cooling of semi-moist petfoods and pet treats compared to conventional petfoods. The same applies for application of liquids. Ottevanger have several options for coating, vacuum coating included. The Ottevanger vacuum coating process allows for layering liquids and attractants
Semi moist petfood requires a different approach to intermediate storage of ﬁnal product to minimise the potential of product damage. The petfood industry has a very wide requirement for ﬁnal product packaging and bagging. Great care is taken to ensure an Ottevanger plant design takes these requirements into account
One of the key issues to successful petfood manufacturing is a process control system designed to meet functional, operational and quality requirements. This includes careful consideration of process Critical Control Points(CCP) and online control of processing parameters.
At Ottevanger Milling Engineers we take great care of the environmental impact of our plant design. This includes the environment inside the processing plant where people have to operate, but also the greater environment outside the processing plant. Health and Safety as well as the control of Dust, Odour , Noise and the Visual Impact of our creations therefore enjoy detailed attention
